uses of a reagent and a compound, and methods for recovering at least one base metal, for recovering a reagent and for extracting at least one base metal

摘要

This application relates to methods of recovering metal from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent having a thiocarbonyl functional group, wherein the concentration of the reagent in the sulfate solution. Acid sulfate is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent to produce a turgid solution containing the metal ions.
